Specification of Letters Patent.

Patented July 21, 1908.

Application led April 23, 1907. Serial No. 369,719.

To all' 'whom it may concern:

Be it known that I, (iiAiiLns WiLLriis, a citizen of the United States of America, residing in Baltimore city, State of" Maryland, United States of America, have invented ce1- tain .new and useful Improvements in Flushing-Tanks, of which the following is a specification.

My present invention relates particularly to the devices for operating the flush valves of what are known as low-down flushing tanks for water closets, etc., but it involves also improved means for attaching the cover to the tank.

In low down'tanks the valve is usually operated by means of a handle or push'but-v ton located at the lower right hand corner of' the tank, and it is sometimes located in the upper middle ortion of the front wall of the When ocated in this last mentioned position, it is necessary for the user of the closet to bend rearward and operate the button with his back. This is an unnatural movement and not always desirable. case first mentioned where the button is located at the lower right hand corner of the tank, the head of the button has been made relatively small and has been operated bv the yhand of the user of the closet. To do this it is necessary to bend the arm backward and turn the hand in an unnatural way to find the button.

According to my invention, I have provided means for operating. the flush valve o which can be actuated by an easy and natural movement of the arm without bendiner the back or twisting the hand.

fy improvements are es ecially designed for use in connection wit i an enameled sheet metal tank such as shown in my Patent No.838,601 of December 18, 1906, in which the water-containing tank is surrounded by a jacket or condensation collector between which and the tank there is an air space preventinJr condensation on the jacket. Such space Iietweenthe front walls of the jacket and the tank, I utilize for mounting part of .the lever connections between the actuating lever and the valve.

The cover of the tank is arched so as to accommodate art of the valve operating mechanism, amil) in order to conveniently connect the cover with the jacket, I form t of the latter with an outwardly projecting flangeon its opposite sides and at its front,

In the.

' wardly projecting flange, b', at the he top and in the front vportion of the flange I f 'orm a downwardly projecting extension constituting part ofa lock for holding the cover in rear corners of the cover are detachably con- 'y nected to the bolts.

ln the accompanying drawings,-l*`igiire l is a perspective view ofsa flush tank embodyjacket by means of screws or mg my improvements, some parts being broken away in order to better illustrate other parts. Fig. 2 is a perspective view of the tank showing its relation with a water `closet seat. Fig. 3 is a perspective view of Fig. 4 is a the cover looking at the inside. perspective view of the tank with the cover removed. Fig. 5 shows a vertical transverse section of the tank with its cover att-ached, and Fig. 6 is a perspective view on an enlarged scale of the valve actuating lever and the horizontally arranged lever with which it is immediately connected.

The water-containing tank, A, is of suhstant-ially .the same construction as that illustrated in my patent before mentioned. and the jacket or condensation collectoi',`B, is also of the same general kind. The cover, (l, is concavo-convex or arched, as shown, to accommodate certain erating mechanism. At the top the jacket is formed with a down-turned rim portion, at the rear, and with a horizontal outtop of its sides and front. At the front the flange, b', is formed with a downwardly projecting extension, b2. The cover, has no flange at its back edge, but it. is formed at the edges ol` its sides and front with a downwardly projecting flange, c, which atl the front is formed with an inwardly projecting extension, c adapted to interlock with the extension, IF, of the flange, fi', of the jacket. The front flange and its extension are preferably curved as shown in order to better take enamel and produce a more pleasing appearance.. In 10g,

connecting the cover with the jacket the former is first placedover the latter and the extension, c', of the flange., c, is made to intei-lock with the extension, fr', of' the flange, b', .then the rear enil of parts` of the valve-opvi IUJ the cover is properly 1i i located and theo posite rear corners thereof are attached to t e opposite rear corners of the top of the jacket. The tank, A, is so held in the jacket, B, as to provide an air space, X, between them. The tank is connected with the flush pipe, D, by suitable couplingsd, preferably such as those shofwn,

and the jacket is connected with the iush pipe by a branch pi e, F. j

The fiush valve, (Iii, is provided with a vertical, stem, g, which extends through a guide bracket, ll, attached to the front wall of the tank` and the upper end of the stem is loosely connected with a vertical rod, I, the upper end of which is jointed to a lever, J, extending horizontally toward one end of the tank and pivoted at, y', to the front wall of the latter near its u per end. This lever, J. is arranged inside tiie tank and it has an arm, J', extending over the top edge thereof, ils outer or front end being adjustably connected with a vertical rod, K, which`extends down through the space X, between the jacket and the tank and has its lower end 'ointed to one end of a horizontallv arranged lever, L, arranged in the space, X, and extending to the opposite side of the tank, be-

ing pivoted at to the front wall of the tank. The rod, l, 'is connected with the longer arm' of the lever, J, and the rod, K, is connected with the longer arm of the intermediate lever, li,

extends-rearwards beneath the adjacent end of the lever, li, while its other or rfront arm is formed with an arm rest, m, of such extended area that the elbow of the user of the closet may, without discomfort, be

placed on it and move it downwards in such.

manner as to raise the short arm of the level', l., )ull down the short arm of the lever, J, an raise the lush valve, G. When the arln of the user is withdrawn the parts assume their normal position after the proper lapse of time, the weight of the valve causing such movement. The arm rest is located some distance forward from the front wall of the f tank so as to be in convenient osition to receivethe elbow of the user of t ie closet.

It will be observed that the user of the closet can actuate the lever, M, very easily and without anv unnatural movement of thel back or twisting of the arm or hand. The leverage is such as to cause the mechanism to operate easily and there is no danger ol' leakage, for, it will be observed, the lever, l.. andl the rod, K, are located in the s ace between the tank and its jacket, the ever, li.

is pivotedl to thetank. and the lever, M, is

arranged some distance above the bottom ol' the jacket so that any water which overflows from the tank into the jacket and all water of condensation and after fill water which enters the jacket will flow out through the pipe, F, to the flush pipe before rising to the evel of the lever, M.

I claim as' my invention :f-

1. The combination of a water-containingand which is operated by said actuating lever, a lever pivoted to the tank and connected with the flush-valve and a rod connecting said lever with the intermediate lever.

2. The combination of a water-containing tank, a jacket surrounding it, a flush valve within the tank, an actuating lever hinged to the front wall of the jacket, an intermediate lever in the spa'ce between the jacket and the tank which is operated by said actuating lever, and operative connections between said intermediate lever and the valve.

3. The combination of a water-containing tank, a jacket surrounding it, and betweenl which and the tank there is an air space, alever within the tank pivoted to the front wall thereof and having an arm projecting over'the top of the tank, a flush valve withwhich said lever is connected, an intermediate. lever within the air space between the. jacket and the tank, a rod connecting this lever with the arm of the first mentioned lever, and an actuatinglever engaging the intermediate lever.

In testimony whereof, I have hereunto subscribed my name.
